The charges were initially brought against investigating officer Botha in 2009, but later withdrawn, according to the police.

Johannesburg: The lead detective in the Oscar Pistorius murder case is himself facing seven attempted murder charges for shooting at a taxi in 2009 to try to stop it, police said Thursday.

"We were only informed on Wednesday that attempted murders charges against Hilton Botha have been reinstated," said police spokesman Neville Malila.

Malila said the charges were initially brought against investigating officer Botha in 2009, but later withdrawn.

It is not clear whether he will continue working on the case.

On Wednesday, Botha's evidence came under scrutiny from Pistorius' defence team, forcing him to admit to multiple errors in the case, including not wearing protective clothing when attending to the athlete's house, where the shooting happened.

Under cross-examination, Botha was forced to admit that Pistorius's version of the early morning shooting last Thursday fitted the crime scene, weakening the state's claim that the killing was premeditated.
